RESUMO
We report the case of a 65-year-old male patient who consulted for swelling of the face and neck after having a pacemaker implantated. Contrast-enhanced chest computerized tomography (CT) confirmed a thrombus within the superior vena cava (SVC). Thus, therapy with oral anticoagulants was initiated, which obtained a good clinical response and resolution of symptoms. A follow-up contrast-enhanced CT scan of the chest and abdomen showed a focal, well-delimited, hyperdense area in the IV hepatic segment during the arterial and portal venous phases, which was associated with persistence of the SVC repletion defect and the presence of multiple superficial venous collaterals in the right anterolateral thoraco-abdominal wall. The hepatic image corresponded to the sign of the "hot spot" or "hot quadrate lobe", a hepatic pseudolesion that should not be confused with other focal hypervascular lesions.

Se presenta un caso de perforación uterina espontánea secundaria a piometra. La perforación uterina es una rara entidad que afecta principalmente a mujeres posmenopáusicas debido a la retención de las secreciones de la cavidad uterina por obstrucción del canal cervical. Su presentación clínica es inespecífica, con dolor abdominal bajo, fiebre, vómitos y datos analíticos de infección, y sus complicaciones potencialmente graves, como peritonitis o shock séptico, de ahí la importancia de su diagnóstico precoz mediante técnicas de imagen (AU)
This paper reports a case of spontaneous perforation due to pyometra. Spontaneous uterine perforation is a rare event that usually affects postmenopausal women. It is secondary to retention of purulent secretions in the uterine cavity caused by obstruction of the cervical canal. The diagnosis is difficult to establish because the clinical presentation is nonspecific and includes abdominal pain, fever, vomiting and laboratory data indicating infection. An early imaging diagnosis is mandatory due to the potentially severe complications of this event such as peritonitis and septic shock (AU)
